Spring Boot Actuator Data

Objective

This project was started from the basic actuator sample. Its java classes only deviate a little from the base sample (just added some initialization). The objective is to use AngularJS to explore the data that the actuator endpoints return.

Deployment

Heroku

• In order to be able to deploy on Heroku, server and management endpoints are kept on the same port (Heroku only supports one). You can update application properties in case you need to do two ports (you would also need to update the managementURL value in the angular app).
• Add the Heroku mvn plugin to your pom.xml and configure it with your application name. Make sure the pom.xml packaging is war. Deploy it with mvn heroku:deploy-war.

Locally

mvn package
java -jar target/dependency/webapp-runner.jar --port 7070 target/gs-actuator-service-0.1.0

• Application is at http://localhost:7070/app/actuate/index.html
  (Credentials config / config)

Examples and screen shots (Heroku)

Check the app is up and running

• Go to https://azonzo.herokuapp.com/hello (It's on Heroku free tier so you may have to wait until app wakes up. Refresh your browser until you stop seeing Heroku Application Error page).

Actuator endpoints

• They are at https://azonzo.herokuapp.com/actuate/{resource}
• Example: https://azonzo.herokuapp.com/actuate/mappings

AngularJS Application

• Go to https://azonzo.herokuapp.com/app/actuate/index.html (credentials config/config)
• Health https://azonzo.herokuapp.com/app/actuate/index.html#/health

• Environment https://azonzo.herokuapp.com/app/actuate/index.html#/env. Each value links to individual URL of environment variable.

Deploy

Point to another actuator

• You can explore actuator data of another application. If need be, you have to provide an authorization (in the form of a header value, Basic Authorzation or Bearer token for instance).
